win32: support "app exec link" reparse points

2023-05-27T07:35:59+00:00

Reparse points with the tag IO_REPARSE_TAG_APPEXECLINK are present in ~/AppData/Local/Microsoft/WindowsApps in Windows 10 and 11. They are: Used by Universal Windows Platform (UWP) packages to encode information that allows the application to be launched by CreateProcess. Modify readlink(2) and lsattr(1) to treat them as symbolic links, in much the same way as was done previously for junctions. They aren't really symbolic links but they're similar. Costs 128-160 bytes. (GitHub issue #327)

lsattr: distinguish between junctions and symlinks

2022-05-19T14:43:23+00:00

Use the new st_tag member of struct stat to display whether a reparse point is a junction or a symlink.

chattr,lsattr: code shrink

2022-05-19T14:43:23+00:00

Drop fgetsetflags() and move its functionality into chattr and lsattr. Raw file attributes are available from struct stat. In chattr don't compile code related to the unused (on Windows) OPT_SET option.
